UNITED STATES PATENT, Orr-1101a:

EDWARD K. RICHARDS, OF CAMBRIDGE, MASSACHUSETTS.

IMPROVEMENT IN PROCESSES FOR SEPARATING SACCHARINE MATTERS FROM AIR.

Specification forming part of Letters Patent No. 199,864, dated January29, 1878; application filed October 26, 1877.

To all whom it may concern:

Be it known that I, EDWARD K. RICHARDS, of Cambridge, in the county ofMiddlesex and State of Massachusetts, have invented Improvements inMethod of Separating Saccharine Matters from Air, of which the followingis a specification:

This invention relates to apparatus for saving floating or otherparticles of sugar carried in the air issuing from sugar-dryingmachinery.

The invention consists in the process herein described of extracting thesaccharine matters from the air issuing from the drying apparatus, ashereinafter described.

Figure 1 represents, in section, the apparatus by which to practice myinvention, such apparatus showing an outer casing provided with shelves,to operate as hereinafter described; and Fig. 2, a section taken throughone of the shelves.

In the drawings, a. represents the case of my apparatus, made as acylinder; but it may be of any suitable size and shape in cross-section.The opening b is to be connected, by pipe 0, (see dotted lines,) with asugar-drying apparatus-a well -known Hersey or other drier-and airforced or drawn through such sugar-drying apparatus will be forcedthrough such pipe and opening into the case. Inside this case isarranged a series of water-spreading shelves, at, rising abovewall-shelves e, the shelves d 0 being so made as to permit water on oneto fall upon the other, and in so doing to cross passages between theshelves, through which the air blown in at 1) travels, as shown by thearrows, such air issuing from the case at f into a suitable chimney.Water is introduced to-the case through pipe g, having at itsdischarging end a cone-shaped water-distributer, h, which, co-operatingwith the first of the water-spreading shelves, there being a narrowspace, a, between the distributer and shelf, causes the water to bethrown out radially as a film or sheet. This water so thrown out strikeseither the interior of the case or the shelf 6, or both, and flowsalternately from pipe 7 below a stop-cock, s, therein.

late from the well to the pipe g, and through the apparatus, for anynumber of times, and when sufficiently sweet may be used to melt the rawsugar.

The lowermost shelf 0 rests on lugs l at the interior of the case, andabove that each shelf is supported, preferably, by legs m resting onanother shelf.

The shelves cl, instead of being conical, as ghown in the drawing, maybe horizontal or The well j will be provided with a gage, p, todetermine the depth of water therein, and with an overflow-pipe, q,fitted to the outletted lines.)

The Hersey drier, fully represented in the United States patents grantedto Charles H. Hersey, has a rotating cylinder, within which is located asystcm'ofsteam-pipes,while through the cylinder, by an exhaust-fan, isdrawn a current of air. This air is forced from the drier into the case,as herein described.

It is considered unnecessary in this application to show in the drawinga sugar-drier.

The water used will be preferably warm.

I claim- In the manufacture of sugar, the process herein described ofseparating saccharinematters from the air after its passage from asugardrying apparatus, consisting in passing such air through sheets orfilms of water, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence'of two subscribing witnesses.

EDWARD K. RICHARDS.
